AbstractThe method of combining RTK unmanned aerial vehicles，geographic information system，forest resource investigationand collctionsystemwith field investigationmainlywereadopted to investigatethedistribution， population area and quantity changes of Rhododendron shanii in 4 places including Baimajian in Huoshan County， AnhuiProvince.The results showed that Rhododendron shanii natural populations was mainlydistributed in4 places in the studyarea： Tianhejian，Baimajian，Duoyunjianand Zhutoujian.Among them，the seedlings of the3 populations of Tianhejian，Baimajianand Duoyunjian were scarce，and thepopulation of Zhutoujian hadless humanactivity.The sedlings under the forest were evenly distributed.Compared withthe populationsurveyresults in 2O12，the population area of Rhododendron shanii in the study area decreased by 11.1hm2 ，the number of population plants decreased by 273，the population habitat was damaged to varying degrees，and the signs of population degradation were obvious in 2024.Based on the geographical distributionand forest age structure of this population，protection countermeasures were proposed from aspects such as strengthening population protection，improving forest stand quality，and promoting artificial breeding，providing references for the near-natural protection and restoration of the populationof Rhododendron shanii.
